To a/LZ whom it may concern:

Be it known that I, JOHN W. LINDoW, a citizen of the United States,residing at Marine City, in the county of St. Clair and State ofMichigan, have invented new and useful Improvements in Extension-Tables,of which the following is a specification.

My invention pertains to extension-tables of the type in which provisionis made for storing supplemental top sections under the top of the mainsection; and it consists in the novel and advantageous combinations ofparts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a longitudinal verticalsection showing my novel table as extended to the full extent. Fig. 2 isa similar view illustrating the table as contracted. Fig. 3 is aninverted plan view illustrating the end extensions of the tableextended. Figs. 4 and 5 are transverse sections taken on the lines 4 4and 5 5 of Figs. 1 and 2, respectively. Fig. 5 is a perspective view ofthe right-hand end extension. Fig. 6 is a detail section illustratingthe relative arrangement of the tongues and grooves of complementaryslides. Figs. 7, 8, and-9 are perspective views of supplemental topsections removed. Fig. 10 is a detail section of the top section shownin Fig. 9. Fig. 11 is an enlarged detail section taken through the topand one side iange of the main section. Fig. 12 is an enlarged detailinverted plan illustrating the manner in which the end bars of the endextensions are seated in rabbets of the side iianges of the main top,and Figs. 13, 14, and 15 are modifications hereinafter referred to indetail.

Referring by letter to the drawings, and more particularly to Figs. 1 to12 thereof, A is the main section of the table. The said main sectioncomprises a top ct, side ianges b, fixed to and depending from the topand having rabbets c in their ends, Figs. 3 and 12, and also havinglongitudinal shelves d on their inner sides at intermediate points oftheir height, and cross-bars e, connected to the lower edges of theflanges The top a and flanges I) arepreferably connected through themedium of angle-irons B, (best shown in Figs. 4,

5, and 11,) and the shelves Z are preferably `formed by metallic plates,as shown, which plates have depending lugs f extending through openingsg in the depending portions of the angle-irons and resting back of saiddepending portions. When desired, however, angle-iron BQ having integralshelves J, Fig. 15, may be employed in lieu of the angle-irons B andshelves (Z without involving a departure from the scope of my invention.

The cross-bars e of the main section A serve for the connection oflongitudinal slides C, which are braced by a cross-bar c and areprovided with inner and outer longitudinal grooves Z and are alsoprovided with tongues m at their ends. At its opposite ends the 65 maintop a is provided with keepers D, Figs. 1 to 3. These keepers D arepreferably metallic pieces connected to the top o, adjacent to the endsthereof, and bent downwardly so that their free portions rest below theunder side of the top, and their ends are flush with tlie ends of thetop.

E E are slides disposed at the inner sides of the slides C and havinglongitudinal grooves p, receiving the tongues m of slides C, Fig. 6, andalso having tongues 2", movable in the inner grooves Z of said slides C,and F is a transverse wall fixed to the slides E. Each of the slides Eis provided on its inner side with eight (more or less) lateralprojections s, while the wall F is provided with recesses t; The saidslides E and wall F constitute the leftend extension of the table. Thisleft-end extension is similar to the right-end extension, except thatthe slides E of the latter are arranged at the outer sides of the slidesC and have their lateral projections s on their outer sides.

G and H, Figs. 1, 7, and 8, are supplemental top sections complementaryto the rightend extension, and G and H are corresponding supplementaltop sections complementary to the left-end extension. These sectionsrespectively comprise a top u and cleats o, fixed to the top andarranged to rest alongside the end slides. In the side of each of thecleats of the section G or G are inclined grooves w, arranged to receivethe lateral projections on the end slides and having offsets at theirupper ends, while in the side of each of the cleats of the section H orH are inclined grooves e, arranged to receive other lateral projectionsof the end slides. The sections G and G' are each further provided atone end of its cleats c with lugs a and at the opposite ends of saidcleats with sockets b. The sections H and H are each further provided atthe inner ends of its cleats with lugs c', arranged to enter the socketsb, and at the outer ends of the cleats with lugs d', arranged to enterthe recesses t in a bar F, all as best shown in Fig. 1.

In the practical use of my novel table whenit is desired to use thesupplemetal sections G G and H H', and thereby increase the length ofthe table, the sections G and G are disposed with their cleats oncertain of the lateral projections of the end slides and their lugs a inthe keepers D of top a, while the sections H Hl are arranged with theircleats on other lateral projections of the end slides, their lugs c inthe sockets b' of sections G G, respectively, and their lugs d in therecesses "of the cross-bars F. With the parts thus relatively arrangedit will be observed that the upper surfaces of the sections G G and H H'rest flush with that of the main section A and the several sections areinterlocked, also that the walls F rest below and support the outeredges of the sectionsH and H. When a table of the length shown in Fig. 2is desired, the'sections G and H are disengaged from each other, as arealso the sections G and H', and are positioned on the end slides so thattheir tops rest directly on said slides, while the grooves in theircleats receive lateral projections on the said slides. With the sectionsG G and H H thus posiytioned relative to the slides the said sectionsare held on the slides in such manner that there is no liability of thesections being casually displaced. From this it follows that when thewalls F are shoved toward the main ection A the sections G G and H Hwill be carried under the top a, and `hence out of sight and out of theway, Fig. 2, while the ends of the walls F will rest in the rabbets c offlanges b, and said walls will rest under the ends of the top a. When itis desired to use the sections G G and H H', the end extensions aredrawn outwardly suiiciently far to enable the inner sections to clearthe top a, when the sections are disengaged from the slides and theoperation first set forth is carried out. When the end extensions aredrawn outwardly as stated, the tongues of their slides bringing upagainst the tongues of the xed slides C will obviously prevent casualdisconnection of the slides E and E from the slides C.

When desirable, vertical grooves we, Fig. 13, maybe provided in thecleats of the sections G G H H in lieu of the grooves before describedwithout involving a departure from thescope of my invention.

When it is desired to omit the shelves Z or d before referred to fromthe table, the side ianges of the main sectionfmay be connected to thetop thereof through the medium of angle-irons B2, one of which is shownin Fig. 14, or through the medium of any other suitable means.

The shelves d on the iianges I) of the main section A are designed tosupport four (more or less) supplemental top sections G2 when the latterare not in use, as shown in Fig. 2. These top sections G2 are identicalin construction, and therefore adetailed description of the one shown inFig. 9 will suffice to impart a definite understanding of all. The saidsection G2, Fig. 9, comprises a top u, cleats fu, preferably of sheetmetal, hinged to the under side of the top u and having lugs a2 andsockets Z22, and springs c2, arranged to move the cleats to and normallyhold the same at right angles to the top. When the several sections G2are not in use, they are stored on the shelves el and between saidshelves and the top a, Figs. 2 and 5, in which position the shelvesw-ill serve to hold the cleats flat against the 'top.. When the sectionsG2 are removed from Linder the top a, the springs c2 will operate tomove the cleats to a position at right angles to the tops, in whichposition the cleats may be arranged on lateral projections of the slidesE E with their lugs and sockets interlocked, as shown in Fig. 1. In thisWay a very long table may be produced, and yet when desired said tablemay be contracted to the extent shown in Fig. 2. To contract the table,the supplemental sections G G H H are placed with their grooves inengagement with the projections of the end slides, and the supplementalsections G2 are placed on the shelves CZ, Fig. 5, after which the endbars F are shoved inwardly into engagement with the ends of the main topa, as shown in Fig. 2. f

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confiningmyself Uto the said specific construction andrelative arrangement of parts, as such changes or modilications may bemade in practice as fairly fall within the scope of my invention asclaimed.
